Abstract
The utility model discloses a kind of pneumatic needle tubing booster, comprise body, in body, be provided with piston valve core, body front end is provided with suction syringe needle, it is characterized in that, also comprises sealed base, and described body rear end is installed on described sealed base; Described sealed base is connected to trachea, and described trachea connects with malleation source of the gas or negative pressure source of the gas via positive/negative pressure controller.Piston valve core of the present utility model directly controls by positive and negative pressure source of the gas, realizes pneumatic control, injects spool by hand without the need to nurse, not only time saving and energy saving, also improves dosing efficiency.
Description
Technical field
This utility model relates to the technical field of medical instruments used in hospital, specifically a kind of pneumatic needle tubing booster.
Background technology
Need before infusing in hospital first to carry out drug solution preparing, for many years, drug solution preparing adopts traditional needle tubing manual operations to complete by nurse always, and process is loaded down with trivial details, and holding time is long.Head nurse's time manual operations syringe needle carries out taking out note action, wastes time and energy, inefficiency.
Utility model content
The purpose of this utility model is just to provide a kind of pneumatic needle tubing booster, to solve existing wasting time and energy in transfusion preparation work in Hospitals at Present, the problem of inefficiency.
This utility model is achieved in that
Pneumatic needle tubing booster, comprises body, in body, is provided with piston valve core, and body front end is provided with suction syringe needle, it is characterized in that, also comprises sealed base, and described body rear end is installed on described sealed base; Described sealed base is connected to trachea, and described trachea connects with malleation source of the gas or negative pressure source of the gas via positive/negative pressure controller.
Under technique scheme, this utility model can realize like this:
Be provided with malleation connecting pipeline and negative pressure connecting pipeline in described positive/negative pressure controller, described malleation connecting pipeline connects with positive pressure pump, and described negative pressure connecting pipeline connects with negative pressure pump; Described trachea controls to be connected with malleation connecting pipeline or negative pressure connecting pipeline via positive/negative pressure controller.
Described positive/negative pressure controller comprises shell body and inner barrel, described trachea is connected on shell body, described malleation connecting pipeline, negative pressure connecting pipeline are positioned at inner barrel and port opens barrel in inner barrel, described trachea, malleation connecting pipeline, negative pressure connecting pipeline three port position are corresponding, when inner barrel relative rotation occurs with shell body via external force, described trachea is selected one and is connected with malleation connecting pipeline, negative pressure connecting pipeline.
This utility model adopts this structure, and the trachea on sealed base controls to make it connect with malleation source of the gas or negative pressure source of the gas via positive/negative pressure controller.When needing to draw feed liquid, when trachea is connected with negative pressure source of the gas, body rear portion forms negative pressure, and piston retreats, and body front portion forms negative pressure, suction needle aspirate feed liquid.When needing to release feed liquid, trachea is connected with malleation source of the gas, body rear portion forms malleation, promotes piston valve core and moves forward, the feed liquid in body is released suction syringe needle.Piston valve core of the present utility model directly controls by positive and negative pressure source of the gas, realizes pneumatic control, injects spool by hand without the need to nurse, not only time saving and energy saving, also improves dosing efficiency.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As shown in Figure 1, pneumatic needle tubing booster comprises body 2, is provided with piston valve core 3 in body, and body front end is provided with suction syringe needle.Pneumatic needle tubing booster also comprises sealed base 4, and body 2 rear end is installed on described sealed base 4.Sealed base 4 is connected to trachea 5, trachea 5 connects with malleation source of the gas or negative pressure source of the gas via positive/negative pressure controller 6, and its connected mode and control mode can have multiple choices.A kind of attainable mode is provided with malleation connecting pipeline 7 and negative pressure connecting pipeline 10 in described positive/negative pressure controller 6, and malleation connecting pipeline 7 connects with positive pressure pump 8.Negative pressure connecting pipeline 10 connects with negative pressure pump 9.Trachea controls to be connected with malleation connecting pipeline or negative pressure connecting pipeline via positive/negative pressure controller, and the mode controlling to be communicated with can have multiple choices.A kind of attainable mode is version positive/negative pressure Controller gain variations being become shell body and inner barrel, trachea 5 is connected on shell body, malleation connecting pipeline 7, negative pressure connecting pipeline 10 is positioned at inner barrel and port opens barrel in inner barrel, trachea 5, malleation connecting pipeline 7, negative pressure connecting pipeline 10 3 port position is corresponding, be exactly specifically be in same axial location, when inner barrel controls relative rotation occurs via external force with shell body, trachea 5 or be connected with malleation connecting pipeline 7, or be connected with negative pressure connecting pipeline 10, or turn off and being communicated with of source of the gas completely.
Work process of the present utility model: suction syringe needle 1 front end is inserted and treats that suction bottle A(is generally distilled water bottle), now, control positive/negative pressure controller, trachea 5 is connected with negative pressure connecting pipeline 10, piston valve core retreats, and the material in material bottle A sucks in needle tubing by suction syringe needle.Its front end is inserted material bottle B to be mixed, now, control positive/negative pressure controller, trachea 5 is connected with malleation connecting pipeline 7, and piston valve core is pushed forward, pushes in material bottle B to be mixed by the material in body by suction syringe needle, realize medicament mixed, complete dosing work.
